What is the solution to the equation? 13 3/4+x=7 1/4

x=-13/2

Step-by-step explanation:

13 3/4=55/4

7 1/4=29/4

55/4+x=29/4

x=29/4-55/4

x=-26/4

simplify

x=-13/2

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
